• Satellite L500 - 19 X - Webcam listed as unknown USB device

  I had problems with my camera is not visible to the software Toshiba or Skype. Restart resolves the problem, but he then disappears again after a while.

  I downloaded the software for the Webcam from the Toshiba support Web page and reinstalled successfully, but now the webcam disappeared completely from the list of devices and shows simply Manager as unknown USB device.

  How can I get it back?

  Hey,.

  Important if you use the webcam: you can use it with one program! That means don't use Skype and webcam software at the same time. For example, if you use it for Skype, close the software of the webcam.

  If the webcam is shown as unknown device, you must reinstall the driver for the webcam I think.
  To control first the software list in Control Panel and remove Camera Assistant Software. After that, you should restart the computer and then reinstall the new software of the webcam.

  Hi waly,.

  Thank you for the information. I suggest that you unplug all USB connections and refresh your laptop. Then try to use your webcam. I think that the problem with the USB connection that gives you the error and not your webcam. Here is a document on how to update your PC to solve problems (Windows 8).

  If you are still experiencing a problem with the webcam and then one of the documents in the previous post should help now. Any stage of document Windows 8 will be the same for Windows 8.1.

  I'm also including this document how trouble Code 43 errors that will help determine which USB product causes the error to appear.

  I hope that this information help, please let me know how it goes.

  Good luck and have a great day!

• Interfacing with several unknown USB devices; all producing NMEA strings

  Hi all

  Question about the peripheral USB interface and their associated drivers.

  I have the obligation to build an application that interacts with the USB devices that produce NMEA strings. I have the library to parse NMEA strings, but I fight with interfacing with several unknown USB devices. When deploying applications, I know not all possible USB devices to use.

  Is it possible to produce one driver who will accept any USB device strings?

  Or, more likely, is there a way to get the LV to recognize a connected USB device and automatically find / install the driver like windows does and is it possible to do in a deployed application?

  I had a trawl of the forums, but I've not found anything that specific.

  Thanks, I really appreciate the help.

  About the VI "set up the serial port", my problem is that the choice of COM port is in a separate menu (not directly related to the VI) and it allows all possible COM ports to be selected. That can be addressed.

  I am not expecting an all-in-one solution but asked the question in case it was possible.

  What I realized, is that for my specific condition to read strings from a USB device. It is likely to be sent over a serial connection. LV can handle this well and easily assuming the device has the installed driver / settings are available.

  LV (and indeed any other program) will not work without a device driver / settings. In this case, parameters set must be found (error) / a USB RAW driver would need to be developed. Devices requirng a RAW USB driver would need a serious review to continue due to the time and effort required. All this effort is work inherited from the AIDS to navigation

  I appreciate any help and I think I got the answer I was looking for! Thank you very much

• M400 - Bluetooth is only recognized as a unknown usb device

  Hello!

  I have a problem with the bluetooth driver / stack. I just got my new M400 and the first time I have activated Bluetooth, battery Setup came - but Windows just said when Setup tried to install the driver that an error has occurred - nothing more.

  The Bluetooth ACPI works very well according to the Device Manager, but that's all. There are no other Bluetooth device list - but an unknown USB device. I compared the device with the id id in the inf file (which is located in the folder of installation of battery). This device is supposed to be the Bluetooth USB Controller-5 of TOSHIBA (USB\VID_0930 & PID_0508) but Windows does not recognize the device - and it is correctly listed in the inf file. Even if I try manually installing the Windows device requires just that the inf file contains no information about the device (which is not true).

  Any ideas what I can do? I already uninstalled the battery and installed the new version of the stack, but it makes no difference.

  Concerning

  Alexander

  I have it solved by myself. There is a defect in the file INF from Toshiba. From the beginning, it lists only Chicago as a compatible Windows version and windows compatibility control is a.

  If you change the string from Chicago to Signature = ' $Windows NT$ ' and out of the chain of compatibility that it all works very well. Unpack the battery Bluetooth to a folder, so just go to 2KXP/Windows/Inf and edit the inf file, then run the setup.exe in the folder 2KXP.

• Code 43 unknown usb device

  I use a laptop HP G20 Windows 7 SP1. Shortly after one of the HP software update, I started getting errors indicating an unknown USB device. I unplugged all USB devices, but the error message still appears. I reinstalled the Realtek USB 2.0 card driver, but the re - install failed. I removed the device to uninstall programs and installed the latest device driver, but it did not help. I noticed that even after I uninstalled the device I was still getting the error message. My USB mouse does not work, but my sony camera works. I am strongly suspect a hardware failure, but I can't find a job anywhere hardware diagnostics.  Please someone help!

• Handspring Visor is a "unrecognized USB device" for Windows XP

  Hello World-

  I feel as if I have a career to synchronize my PDA hot! I used to hotsync regularly on my old HP Windows 98 machine, and now that I have this new (er) eMachines Windows XP Pro system, I got nothing but heartache. Here's the situation:

  My Visor Deluxe runs Palm OS 3.1H3, apparently the latest version which will work with it. The computer is running Windows XP Pro SP2. I have hotsync a few times when I got to the computer, but it has never been reliable. Now I surely CAN NOT synchronize! When I press the button on the cradle, Windows hotsync ALWAYS reports, "USB device not recognized" and of course the visor says he couldn't make contact with the office.

  HotSync manager is running (I have the blue and red arrow on the taskbar icon), and if I look at the Device Manager when I try to sync, is apparently trying to get the driver, he simply painted the same list. The list does NOT include the Palm, Handspring or unknown devices.

  I followed the directions "clean uninstall" I found on this forum and re-installed Palm Desktop 4.01. That worked once a week or two ago, but now when I arrive at the end of the installation, when I'm supposed to hot sync, I get the error not recognized USB.  I even tried to install Palm Desktop software version 6.2, but which ended up in a mess - I was getting errors like "Ordinal 23 could not bewildered because of the trajectory messed up', or words to that effect... I think it's ok for XP, but not "peripheral" as my trusty old visor :-)

  I know I should try to use the same configuration on another computer to be sure that the visor is ok, but I don't have access to another machine; In addition, the PDA has no other wierdness. Soft resets do nothing, but I don't want to try a hard reset until I get everything synced to the top! I am at my wit's end and don't know what else to try. I tried both my cribs and a number of different USB connections both at the front and the back of the PC. The USB hardware in the computer seems to be fine with everything else - mouse, camera, mp3, flash drives. I'm beginning to suspect that I need to plug with USB 1 and these are 2 USB, but I don't know how to check either of these things, or how "throttle" in the case, I have to use the USB as soon as possible.

  Thanks in advance to everyone that these figures. I'll be very grateful to have everything works again.

  I was with you until the end. I hate to ask, but could you clarify this just a little:

  Then, reinstall your Palm desktop from the CD and do a hotsync. If she asks
  for a user name and you synchronized your device before you put "test" If you "
  no sync before creating a hotsync name.

  Ok. I read three "if" statements, and try to understand what is meant here. If they ask you a user name AND if I synced before, AND if I do not synchronize before creating a hotsync name, I put in 'test '. Means I can't use the name I used for this camera? Or are you suggesting that, really, should I open Palm Desktop and create the username before I hotsync for the first time (after the new installation)?

  I * have * synchronized before, and I don't plan to sync until everything is set up right, which to me should mean that Palm Desktop is ready with a username to match your handheld.

  Also, these indications seem in conflict which advised you to in the first paragraph, where you said:

  When you install Palm desktop, skip the hotsync process and complete the installation. After installation, adjust the conduit in hotsync manager for handheld overrides desktop, then synchronize with PC. During the connection process, it will ask you a username, enter the same username which is located in the upper right of the screen on your handheld hotsync.

  It * seems * that what you say I have to do is:

  (A) clean uninstall - move data to safe places, uninstall, and then remove all traces of "Palm" and "Handspring" of the registry.

  (B) restart the computer.

  (C) install Palm desktop, but not hot sync again.

  (D) open Palm Desktop, add the user name (Tools/users) and set the lines for handheld overrides Desktop.

  (E) hot sync.

  Isn't it? Sorry to be so simple, but I want to make sure to proceed exactly right. Thank you very much for your reply and for your help.

  Step 1.  Identify the make and model of the USB device.
  Step 2: Identify the version of Windows XP you have, including service pack (start > run > winver > OK)

  Although the following steps 1 & 2 you could get extra help, I suspect that the 'USB device' has indeed "defective" and you have to go back to where you got it and request a refund or a replacement.
